Description
Cynk krystalizuje sie w dwóch odmia¬ nach; najczesciej ma sie do czynienia z dobrze znana odmiana zwana (3, podczas gdy cynk a otrzymuje sie tylko w scisle okreslonych warunkach. Odmiane a od¬ kryl le Chatelier; temperatura przemiany wynosi okolo 350°C i jest zawarta w kaz¬ dym razie w granicach od 340°—360°C, Przedmiot niniejszego wynalazku sta¬ nowi olowiany stop lozyskowy zawierajacy cynk nie w postaci P, lecz w postaci a, który nadaje wymienionemu stopowi wla¬ snosci odmienne niz cynk (3 Mianowicie mala domieszka cynku a zwieksza wytrzy¬ malosc olowiu na zgniatanie i jego kowal- nosc w takim stopniu, ze takie stopy olowiu i cynku nadaja sie bardzo dobrze do uzytku jako metale lozyskowe.Przemiana postaci cynku P powstaja¬ ca w okresie tezenia na postac a zachodzi w specjalnych warunkach, których tech¬ niczne urzeczywistnienie jest przedmiotem niniejszego wynalazku. Jak wiadomo prze¬ miana ta zachodzi tern trudniej, im czyst¬ szy jest cynk; próby wynalazcy wykaza¬ ly, ze przemiane te przyspiesza obecnosc obcych metali, lecz tylko tych, które nale¬ za do tej samej grupy ukladu perjodycz- nego lub grupy bezposrednio poprzedzaja¬ cej. Do tych metali nalezy kadm, bar, rtec, beryl, magnez i t. d. oraz miedz, lit, sód, potas i t d. Metale te dodane do stopu o- lowiu zawierajacego do 5% cynku przy¬ spieszaja pirzemiane cynku ,3 na a o ile jest zachowany jeszcze inny warunek, a mianowicie powolne ochladzanie do tern-s^ peratury przemiany. Z tego powodu ochla¬ dzanie stopu w granicach od 360° do 340°C powinno byc mozliwie powolne, przyczem stop nie powinien podlegac wstrzasnieniom, aby odlew nie byl porowaty. W tych wa¬ runkach cynk tezeje calkowicie lub prze¬ waznie w postaci a, a stop posiada wla¬ snosci wymienione powyzej tak, ze odpo¬ wiada wymaganiom stosowanym do sto¬ pów lozyskowych. PLZinc crystallizes in two forms; Most often it is a well-known variety called (3, while zinc a is obtained only under strictly defined conditions. Variation and the discovery of Chatelier; from 340 ° -360 ° C. The subject of the present invention is a lead bearing alloy containing zinc not in the P form, but in the α form, which gives said alloy properties different than zinc (3 Namely, a small addition of zinc and increases the strength lead to crushability and its smitability to such an extent that such lead-zinc alloys are very well suited for use as bearing metals. The transformation of the zinc P form, which occurs during the thesis period, into the form of a takes place under special conditions, which technically the subject of the present invention, this transformation is known to be more difficult, the purer the zinc is; the inventor's tests have shown that the transformation is accelerated by the presence of foreign metals, but only those that belong to the same group in the periodic system or the group immediately preceding it. These metals include cadmium, barium, mercury, beryllium, magnesium, etc., as well as copper, lithium, sodium, potassium, etc. When added to a lead alloy containing up to 5% zinc, these metals accelerate the zinc foams, 3 as far as possible. Yet another condition was met, namely slow cooling down to the transition temperature. For this reason, cooling of the alloy from 360 ° to 340 ° C should be as slow as possible, and the alloy should not be subjected to vibrations so that the casting is not porous. Under these conditions the zinc is wholly or mostly in the α form, and the alloy has the properties mentioned above so as to conform to the requirements applicable to the bearing alloys. PL
